What part of the brain is responsible for dexterity?
The cerebellum is located behind the brain stem. While the frontal lobe controls movement, the cerebellum “fine-tunes” this movement. This area of the brain is responsible for fine motor movement, balance, and the brain’s ability to determine limb position.
What affects hand dexterity?
The factors associated with hand dexterity were age in dominant hands (R2 = 0.321) and age and thickness of the second and third fingers in nondominant hands (R2 = 0.282). Conclusion: FDT scores increased with increasing age for both dominant and nondominant hands.
